1. Sand moxibustion can dispel cold and dampness, dredge channels and collaterals, remove blood stasis and dissipate stagnation, promote circulation of qi and blood circulation, relieve swelling and pain, remove toxin and clear heat, regulate the balance of yin and yang, eliminate fatigue and strengthen the body, thus achieving the purpose of strengthening the body resistance, eliminating pathogenic factors and treating diseases. So many diseases can be treated with hot sand moxibustion. Hot sand moxibustion can slowly suck out the water in the focus and promote local blood circulation at the same time, so as to achieve the purpose of relieving pain and restoring function, thus treating rheumatism, "joint pain" and other discomfort.
Second, sand moxibustion has the functions of promoting qi and blood circulation, relaxing tendons and activating collaterals, relieving swelling and pain, expelling wind and removing dampness in the self-regulation of the body, which plays a benign stimulating role and promotes its normal function.
Third, hot sand moxibustion can dilate blood vessels, promote local blood circulation, improve congestion, strengthen metabolism, accelerate the discharge of wastes and toxins in the body, change the nutritional status of local tissues, enhance the permeability of blood vessel walls, enhance the phagocytic activity of white blood cells and reticular cells, enhance local tolerance and body resistance, and play the role of warming meridians, dispelling cold, clearing heat and detoxifying, thus achieving the purpose of promoting disease improvement.
Fourthly, sand moxibustion can regulate the nervous system. Due to self-hemolysis, a series of benign stimuli are given to the body, which act on the peripheral receptors of the nervous system and are transmitted to the heart and reach the cerebral cortex.
5. The warm stimulation of sand moxibustion on the skin is transmitted to the central nervous system through the reflex pathways of skin receptors and vascular receptors, resulting in reflective excitement, thus regulating the excitement and inhibition process of the cerebral cortex, making it tend to be balanced, strengthening the regulatory function of the cerebral cortex on various parts of the body, making the corresponding tissues of the affected skin metabolize vigorously, enhancing the phagocytosis, recovering the body, adjusting the imbalance of Yin and Yang, and gradually curing the disease.
Six, sand moxibustion can improve metabolism under the regulation of microcirculation. The main function of microcirculation is the exchange of substances between blood and tissues, and the regulation of its function is of great significance in physiology and pathology. But also can strengthen lymphatic circulation and make the phagocytosis of lymphocytes active. In addition, due to hemolysis after sand moxibustion, a histamine-like substance is immediately produced, which flows all over the body with body fluids, stimulates various organs, enhances their functional vitality, and contributes to the recovery of body functions.
